基于MPPT的太阳能充电控制器的设计

本文设计了一种具有MPPT功能的光伏发电充电控制器。通过单片机检测蓄电池充电电压、充电电流的大小,自动切换充电器的工作状态,有效地提高了蓄电池的寿命。在光照条件不足时,蓄电池的电压,电流未超出给定值,开启MPPT功能,保证整个系统最大效率的充电。经matlab仿真,该设计具有可行性。

This paper designs a photovoltaic power charging controller with MPPT function. The machine can detect the charging voltage of the battery, the size of charging current, and automatically switch the working state of the charger, effectively improving the battery life. When the lighting condition is insufficient, the voltage of the accumulator is not exceeding the given value, and the MPPT function is opened to ensure the maximum efficiency of the whole system. Through Matlab simulation, the design is feasible
